Definitions

  • the present invention relates to orthopaedic implants. More particularly, the present invention relates to articular bearing surfaces for orthopaedic implants.
  • an orthopaedic knee implant may include a femoral component for replacing the femoral articulating condyles and a tibial component for replacing the tibial articulating surface.
  • the femoral component typically includes a metallic articulating bearing surface which glides and pivots on a non-metallic articulating bearing surface of the tibial component.
  • knee implants comprise a femoral component made of a metal such as Ti-6Al-4V alloy or Cobalt-Chromium-Molybdenum alloy and a tibial bearing surface made of ultra high molecular weight polyethylene (UHMWPE).
  • a femoral component made of a metal such as Ti-6Al-4V alloy or Cobalt-Chromium-Molybdenum alloy
  • a tibial bearing surface made of ultra high molecular weight polyethylene (UHMWPE).
  • UHMWPE ultra high molecular weight polyethylene
  • the implant components may include constraint mechanisms to provide some degree of constraint to the motion permitted between the components. These constraint mechanisms may replace or augment natural constraint in the joint such as that provided by tendons and ligaments crossing the joint. These constraint mechanisms may provide the function of missing or damaged natural constraints.
  • the tibial articular surface may include a post that projects upwardly to interact with a cam and box formed on the femoral component to limit rotation, varus/valgus tipping, anterior/posterior translation, posterior rollback, and/or other parameters of knee motion.
  • Such constraint mechanisms may see significant bending, shear, and even impact loads within the limits of normal operation. Therefore, it is generally desirable for the constraint mechanism components to have high strength and toughness. Furthermore, the constraint mechanisms have limits to the permissible wear that can occur between contacting surfaces.
  • a particular type of implant has an articular bearing surface for which low wear is of prime importance and which further includes a constraint mechanism portion for which strength and toughness are of prime importance.
  • a posterior stabilized knee it is desirable for the articular condyles to exhibit low wear and the tibial post to exhibit high strength and toughness.
  • the present invention provides an implant for replacing an articulating bone end adjacent a skeletal joint as defined in claim 1 and a tibial bearing component for replacing a portion of the proximal tibial surface of a knee joint as defined in claim 3.
  • an implant in one aspect of the invention, includes first and second components to replace a portion of each of a pair of opposed articulating bone ends.
  • the second component has means for low friction articulation with the first component and means for engaging the first component to constrain the motion between the components.
  • the means for low friction articulation includes a first material exhibiting low wear and having a predetermined toughness value.
  • the means for engaging includes a second material having a predetermined toughness value higher than the means for low friction articulation.
  • a tibial bearing component for replacing a portion of the proximal tibial surface of a knee joint includes a first portion having a bearing surface.
  • the bearing surface has a region exhibiting low wear and has a first predetermined toughness value.
  • the tibial bearing component includes a second portion having an intercondylar region.
  • the intercondylar region has a region having a second predetermined toughness value that is greater than the first predetermined toughness value.
  • the first and second portions are joined together to form a tibial bearing component.
  • a tibial implant for a knee joint in another aspect of the invention, includes first and second bearing portions. Each of the first and second bearing portions includes an articular surface having a first predetermined toughness value. An intercondylar portion is interposed between the first and second bearing portions. The intercondylar portion has a second predetermined toughness value greater then the first predetermined toughness value of the bearing portions.
  • the articulating joint construction of the present invention may be used in implants for any articulating joint, including for example, the articulating joints of the skeletal system.
  • the construction may be incorporated into implants for the hip, knee, shoulder, vertebrae, elbow, wrist, ankle, jaw, and digits.
  • a tibial knee component is depicted, although it will be understood by those skilled in the art that this invention may be suitable for other applications as well.
  • FIGS. 1-3 illustrate a tibial knee component 10 including an articular bearing insert 12 and a supporting tray 14.
  • the tray 14 includes an upper portion 16 for receiving the bearing insert 12 and a stem extension 18 for insertion into the tibial bone to hold the tray 14 in place.
  • the bearing insert 12 is divided into three discrete portions including two outer condylar components 20 and an intercondylar component 22.
  • the condylar components 20 each include an articular surface 24 for low friction articulation with a femoral component (not shown).
  • the articular surfaces 24 may be made of UHMWPE. It is desirable to minimize the wear between the articular surfaces 24 and the femoral component.
  • the articular surfaces 24 may be made of relatively hard and/or brittle materials that exhibit low wear.
  • An example is highly crosslinked UHMWPE. This material easily meet the strength requirements for the articular surfaces 24 since the articular surfaces 24 are primarily loaded in compression.
  • chemicals and/or radiation to highly crosslink UHMWPE to improve its wear properties.
  • Various forms of irradiation may be used including gamma and electron beam irradiation.
  • UHMWPE medical devices are commonly irradiated to sterilize them.
  • the irradiation dose for sterilization is approximately in the range of 2.5-3.7 Mrad. This dose range may result in lightly cross linked UHMWPE, but it does not result in an appreciable improvement in wear characteristics.
  • non-ionizing radiation, ethylene oxide gas, and other non-crosslinking forms of sterilization may be used that result in non-crosslinked polyethylene.
  • the degree of crosslinking may be described in terms of the average molecular weight between crosslinks. For UHMWPE that has been gamma irradiated at low dose for sterilization purposes, the molecular weight between crosslinks is on the order of 8800 grams per mole.
  • the average molecular weight between crosslinks is on the order of 3000-4000 grams per mole.
  • Another way to describe the degree of crosslinking is in terms of swell ratio. In this measurement, a sample of the polyethylene is exposed to a solvent. As the sample absorbs the solvent, it swells. Crosslinks inhibit the swelling. Thus the ratio of the size of the swollen sample to its original size yields a measure of the degree of crosslinking. For UHMWPE that has been gamma irradiated at low dose for sterilization purposes, the swell ratio is on the order of about 3.68. For highly crosslinked polyethylene, the swell ratio is on the order of about 2.3.
  • the intercondylar component 22 includes a tibial eminence 26 for engaging a box and/or cam formed on the femoral component to constrain the amount of relative motion permitted between the femoral and tibial 10 components.
  • the tibial eminence 26 is subjected to a combination of loads including shear, bending, and impacts. Therefore, it is desirable for the tibial eminence 26 to be made of a material that is relatively tough and impact resistant.
  • the eminence may also be made of UHMWPE.
  • the condylar components 20 and intercondylar component 22 are made from materials having different properties tailored to the expected loading of the different components.
  • the condylar components 20 may be made of materials that exhibit relatively low wear. This wear is typically quantified by measuring the weight loss exhibited by articulating components.
  • the intercondylar components may be made of materials that exhibit relatively high toughness. Toughness may be described as the amount of energy required to cause a material to fail.
  • One measure of toughness is fracture impact toughness measured by determining the amount of energy required to break notched samples with a calibrated pendulum.
  • Tensile failure toughness can be gauged by measuring the area under a load/displacement curve.
  • the condylar components 20 may be made of highly crosslinked UHMWPE while the intercondylar component 22 may be made of lightly or non-crosslinked UHMWPE.
  • the condylar components 20 and intercondylar component 22 may be joined together to form the tibial bearing insert 12 in a variety of ways.
  • the components may be provided as a modular kit of parts that are joined together intraoperatively by the surgical staff to permit customizing the implant to a particular patients needs.
  • the components may be permanently joined together at the time of manufacturing and supplied as a one piece tibial bearing insert 12.
  • the components may be permanently joined by bonding, by press fitting, or by molding them together in an interdigitating manner.
  • the components may be press fit into the tray 14 to keep them in their proper relative positions.
  • the components may be joined by mechanical fasteners.
  • the tray may be omitted and the tibial bearing insert 12 configured to be placed directly on the tibial bone.
